To all 'whom it may con-cem: f

Be it known that I, Loc-AN T. MoMnNnMY, a citizen of the United ctates,residing in Chicago, in the county of Cook and State of Illinois, haveinvented anew vand useful Improvement in Service-Requirement Indicators for Automobiles, ofwhich the .following is a specification.

My present inventio'nfprelates tov an indi-f eating device for advising the user of an automobile of the periods when attention i should be given to the oiling or other care of the car. f

A primary objiect of the invention is Y.the provision of av device adapted to bel associated with the speedometer,

Y vpearance, asjwell as convenient and satisfacthe accompanying tory in operation. A

Numerous other objects and. advantages of the invention willbe apparent as it is better understood from the following description, which, takenl inl connection wit drawings, discloses a preferred embodiment thereof. Referring to the drawings:

. Figl is a front elevation of a portion ot an automobile dash to. v'which av device 'embodying my invention. is applied; y. f

Fig. 2 isa sectional view'thereof taken Vsubstantially onthe section lineV 2--2 of Fei;

Fig. 3 is an elevational view of the interior of the holder; and V Fig. l is anelevational view of one of the instruction envelopes having indicatng'numerals -thereon for a purpose which will hereinafter appear. Y Y

The device as thus illustrated, comprises a holder 21, vwhich is mounted behind the dash 22, and inthe present instance, lconsists. of a back 23 and a body part 24 to' which the back is secured by means of screws 25. The holder is secured to the dash lby means of a ring 26 having peripheral groove adapted toI receive the body edges surrounding an opening in the front wall 28 of said body, said ring extending through thevdash 22 and being 'held in place by means of a lock-nut 29, which is threaded on to said ringl and provided with a front flange 3i adapted to hold a glass disk or crystal 32 against the front edges of the ring 26. This construction not only serves to secure the holder 2 in place, but also provides asight opeiiing through which the indicating means y i maybe seen. The holder 21 n and' which is. both simple in construction and neat in apmembers 38 secured by rivets back member v23, and it will be understood V provided with flaps 'when the reading on been given o an extends `through an opening in the bottom flange 33 ofthe dash and protrudes below said d`ash,}being heldagainstswinging nioveinent on the ring 26 by means of Vbrackets 34. The lower part of the holder which protrudes beneaththe dash is provided with a'front 'opening- 35.

Saidholder is Aadapted to contain means for indicating to the driver the speedometer mileage reading at whichattention should nent, be given totheoiling or other care of the car, and I prefer employing lfor this'lpurpose a plurality of envelopes 36,upon which indicating,numerals 37 are placed in 'such position that they may be seen through the sight opening hereinbefore described, when the envelopes are arranged in normal position in the holder. It is contemplated by the invention that said envelopes may vcontain instruction charts or sheets which may bel referred to by 4formation as to service required.

The envelopes are held towardthe front of the holderfby means ofja plurality of spring 39 to the holder that said ,envelopes may be so arranged that withdrawal ofthe front one thereof. will present to view another bearing the lnent mileageV readingat which-the driver should attend to oiling the car. The envelopes are,V

are atithebottom thereof 4and protrudey from Y the opening 35, so that they may be readily grasped to withdraw the envelope when the mileage reading 37 thereon corresponds with the speedometer.

the reading on p Said speedometer may be of any usual form as I have shown on the drawings, meredial 42 having a mileage indicator43, la trip indicator la and a speed indicator 45, all of which will be readily understood.

I will' be evident that when the envelopes are appropriately arranged in the holder 21, the mileage period at which service will next be required will be clearly indicated, Vand corresponds with the reading 37 of the front envelope 36, the driver will be reminded that'VV the attention period has arrived, and if the speedometer reading passes the reading on the envelope,he will be continually reminded of his neglect until the required attention has d the front envelope withdrawn. y i

It is thought that the invention and many al, lwhich preferably the user of the car for ini the mileage indicator 43 zmobiles,

led to register with said holder extending beneath the dash and of its. attendant` advantages will be understoodfroin the foregoing description, and it will be apparent that various be made in the form, construction and arrangement of the parts Without departing from the spirit and==seope of the invention -or sacrificing all of its material advantages, the form hereinbefore described being'merely` a preferred embodiment thereof.
